[asterisk-users] HELP! AGI AUTOHANGUP does not seem to hangup the channel.

[Jonathan H]

I think I can confidently say, after most of a day and reading the following....

https://stackoverflow.com/questions/66768885/why-doesnt-asterisk-17-catch-hangup-request-from-pjsip-client-solved
https://wiki.asterisk.org/wiki/display/AST/Asterisk+18+AGICommand_set+autohangup

https://wiki.asterisk.org/wiki/display/AST/Asterisk+18+Function_PJSIP_ENDPOINT
https://wiki.asterisk.org/wiki/display/AST/Asterisk+18+Configuration_res_pjsip

... that Asterisk doesn't like mixing autoHangup with AGI, and there
appears to be no way of the ts-agi library I'm using knowing that it
has autoHungup, so it can't close the AGI connection which seems to
release Asterisk to hangup properly.

I had thought that the AGIEXITONHANGUP variable might help, but it
appears to do nothing, although I'm unsure if I'm setting it correctly
as:

Here it says the flag is "1"
https://wiki.asterisk.org/wiki/display/AST/Asterisk+Standard+Channel+Variables

And here it says the flag is "yes"
https://wiki.asterisk.org/wiki/display/AST/Asterisk+18+Application_AGI

That said, I wish I could use ARI not AGI but without the current
media offset available on ARI, I need AGI :)

So for now, the workaround is to forget about setting autohangup, and
just hangup the caller manually at the point they don't over-ride the
timeout.

Thanks!
